| Read the passage given below and answer the following question. According to Hardy-Weinberg principle, the allele frequencies in a population are stable and remain constant through generations. The gene pool (total genes and their alleles in a population) remains a constant. This is called genetic equilibrium .Sum total of all the allelic frequencies is 1. (A) Write the equation representing Hardy-Weinberg equilibrium. |
| List the factors that affect the genetic equilibrium. |
(i)Genetic drift
(ii)Mutation
(iii)Genetic recombination
(iv)Natural selection (i) Mutation
(ii)Natural selection
(iii)Random mating (i)Random mating
(ii)Gene flow
(iii)No recombination (i)No recombination
(ii)Random mating
(iii)Natural selection
(iv)Gene flow |
| (i)Genetic drift (ii)Mutation (iii)Genetic recombination (iv)Natural selection |
| The factors which affect the Hardy Weinberg equilibrium are: gene migration or gene flow , genetic drift , mutation, genetic recombination and natural selection. When migration of a section of population to another place occurs , gene frequencies change in the original as well as in the new population . |
